DISK PULVERIZER.

To dll whom it may concern.'

Be it known that I, FRANKLIN M. Iman, a citizen of the United States, residingat Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Disk Pulverizcrs; and I do hereby declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same."

My invention relates to improvement in disk pulverizers and the object of my invention is to produce a machine of this type which will grind hard materials, such as ore, quickly and to the desired degree of neness, and which will wear evenly.

1With this object in view, my invention consists in the construction and combinations of parts as hereinafter described and claimed.

ln the accompanying drawings-Figure 1 is a side view of my invention. Fig. 2 is a longitudinal central section thereof. Fig. 3 is a cross section thereof on the line 3-3 of Fig. 2, looking in the direction of the arrows. Fig. 4 is a top plan view' of the vi brating casting detached. Fig. 5 is a side view of the same. Fig. 6 is an end view of the same. Fig. 7 is an end view of the rotary crushing disk, and Fig. 8 is an end view of the vibrating crushing disk.

1 represents a heavy casting fastened to a suitable support b-y bolts 2. This casting extends upwardly to form supports 3 and 4, through which the main shaft passes, and has a curved portion 5, encircling a worm wheel hereinafter referred to.

6 represents the driving shaft, with a loose pulley 7 and a fast pulley 8 mounted thereon. This shaft has an enlargement 9 thereon, terminating in a worm 10. This shaft is supported near one end in the part 4 and in a sleeve 11 screwed into the part 3. The sleeve 11 is provided with an enlargement 12, having holes 13 into which a bar or wrench may be inserted to adjust the shaft 6 in the casing 1. Theshaft 6 has one end reduced in diameter, as shown at 14, and on this reduced portion is permanently fastened a perforated disk 15. The end of the shaft may be upset to hold said disk in place, or said disk may be secured to said shaft in any desired way.

16 represents the rotary grinding disk, which is secured to the disk 15 by bolts 17.

As shown in Fig. 7, this disk is provided with a face forming a portion of a sphere and with cut away portions 18, forming pocket-s in which the ore or other material may collect. The shaft G is provided with any well known means for lubricating it.

Mounted on the stationary casing l is the casting 19, which carries the vibrating disk. This casting is provided with two rearwardly extending ears 20, Fig. 4, through which pass pins 21, which pins are mounted in the easing 1. Therefore the whole casting is free to revolve on the pins 21. The sides of this casting are strengthened by ribs 22. The casting is also provided with an upwardly extending portion 23, having en largements 24, in which is mounted a shaft 25, by means of which the casting is vibrated, as hereinafter described. This cast ing is also provided with an opening 2G, in which is located an oil cup 27 for lubricating the shaft (i, and in fact every part ofthe device may be lubricated as desired. front 28 of the casting 19 is considerably enlarged, as shown in Fig. 5, and is provided with a central upwardly projecting boss 29, which is perforated for the reception of the shaft 30, and on this shaft 30 is supported the casing 3l, which carries the hopper' and which is provided with the concave vibratory grinding disk 32. The casing 31 is nearly cylindrical in shape, except that its lower part is open, as shown in Fig. 2, to allow the ore, or other material, to be freply discharged after it has been` ground. The casing 31 is also provided with upwardly and rearwardly projecting ears 33, which are journaled on the shaft 30. The casing 31 is expanded to forni a hopper 34, although this may be made in a separatepiece and bolted thereto, if desired. The concave grinding disk 32 is attached to the front end of the casing by screws 38, passing through said casing and into the openings 35. The disk 32 is also provided with a central opening 36, through which the material is fed to the casing, and with depressions forming `pockets 37, indicated in dotted liifes in Fig.

2, which correspond to some of the pockets 18 in the grinding disk 16. The inward curve of the concave portion of the disk 32 is practically the same as the convex curve of the disk 16.

`The casing 31 is attached to the casting 19 in the following manner: On the casting 19 are formed parallel lugs 38, through which The passes a vertical pin 39.v On this pin is journaled a swinging pin 40, screw-threaded as shown at 41, and provided with an adjusting head 42. The casing 31 is provided with projecting ears 43, between which the pin 40 is adapted to be swung, the construction being the same on both sides. The parts being in the position shown in Fig. 1 and the heads 42 being turned as far as possible, the casing 31 will be tightly held against the casting 19.

The means for vibrating the casting 19 will next be described.

44 represents a shaft journaled in enlargements 45 of the casing` 1, said shaft being fixedly mounted therein by means of screws 46. On the shaft 44 is mounted a sleeve 47, on the central part of which is a worm wheel 48, which engages with the worm 10 on the shaft 6. The ends of the sleeve 47 are turned down so as to form eccentric portions 49, as clearly indicated in Fig. 3 and shown in dotted lines in Fig. 2. On these eccentric port-ions are mounted upwardly projecting arms 50, each provided with an enlargement 51, the construction of the two arms being similar, and the enlarged portions 51 engage with the shaft 25.

The operation is as follows: The shaft 6 being set in motion by the pulley 8 revolves the disk 16 continuously in a single plane. At the same time, the motion of this shaft, by means of the worm 10, worm wheel 48, and connections just described, moves the casting 19, carrying with it the casing 31, in which is fixed the concave disk 32, so that said casting and casing vibrate around the pins 21. Material being f ed' in through the opening 34, is caught between the rotating and vibrating disks and quickly and thoroughly pulverized, and the vibratory motion prevents the material from wearing grooves in JErhe disks, as often happens in disk pulverizers. The grinding action is aided by the fact that the ore, or other material, collects in the pockets 18 and 37. When thoroughly ground, the material drops through the lower open part of the casing 31 into a suitable receptacle.

While I have thus described my invention, I wish it to be distinctly understood that I do not limit myself to the exact construction shown and described, as this could be varied from inmany particulars without departing from the spirit of my invention.

I claim 1. In. adisk pulverizer, the combination of a supporting framework, a rotatable disk having a convex face, means for rotating said disk, a casting provided with a disk having a concave face of substantially the same curvature as the curvature of the convex faced disk, said casting and concave disk being provided with feed openings, and devices for vibrating said casting in a plane passing through the centers of the disks and of the means for rotating the convex faced disk, substantially as described.

2. In a disk pulverizer, the combination of a supporting framework, a rotatable disk carried thereby and having a convex face, means for rotating said disk, a casting pivotally supported on said framework and having a concave faced disk of substantially the same curvature as said first named disk, said casting and concave disk being provided with feed openings, said casting being pivotally supported on said framework in the same plane as said means and at a point corresponding to the center of the sphere of the surface of which the rotatable disk forms a part, and devices driven by the operating means for reciprocating said easting in a vertical line, substantially as described.

3. In a disk pulverizer, the combination of a supporting frame, a shaft mounted therein, a disk having a convex face and fixed to said shaft, a casting pivotally mounted on said frame, a disk having a concave face, supported by said casting, and means including` a worm on said shaft and a worm wheel for vibrating said casting by the movement of said shaft, substantially as described.

4. In a disk pulverizer, the combination of a supporting frame, a shaft j ournaled therein, means for adjusting said shaft in said frame, a disk having a convex face and fixed to one end of said shaft, a casting pivotally mounted on said frame, a sleeve provided with a worm wheel engaging a worm on said shaft, said sleeve having eccentric portions and a concave disk supported thereby, and arms connected to the eccentric portions of said sleeve and to said casting, substantially as described.

In testimony whereof, I aiiix my signa ture, in presence of two witnesses.
